Patent GB-1170667-A (GB)
Title: Machines such as Presses for Sheet Material such as Cardboard including Sheet Feeding Mechanism
IPC: B26F1/40
Filed: 1967-06-14
Abstract: 1,170,667. Feeding sheets. J. BOBST ET FILS S.A. 14 June, 1967 [21 June, 1966], No. 27383/67. Heading B8R. Sheet-feeding apparatus comprises gripper bars carried on chains driven by sprockets wherein the sprockets are caused to perform predetermined angular displacements, alternating with periods of immobility, an additional angular feed movement being imparted at the start of each period of immobility in order to bring the sheets up against e.g. registering stops. This is especially applicable to a platen press such as that described in Specification 972,416 wherein sheets are picked up at one station, and processed at another, movable stops being provided at each station for registration of the sheets, and the additional feed movement bringing the sheets against the stops (Fig. 1, not shown). The details of the mechanism are illustrated in Fig. 2 wherein a conveyer chain 28 is driven by sprockets 27 mounted on a shaft 26 which is in turn driven in one direction only by a toothed quadrant (not shown). A cam 29 is fixed to the shaft 26 and a locking roller 30 carried on a rocker 31 is periodically forced into a notch 32 on the cam 29, this function being controlled by a cam 33 via cam roller 38, lever 34, link 36 and pin 52; the link 36 is acted on by a spring 37 which ensures that roller 38 presses against cam 33; the rocker 31 is pivoted at 39 on a lever 40 which is concentric of shaft 26 and normally bears against an adjustable stop 41. In action, the cam 37 rotates continuously; when the cam roller 38 bears on the smallest radius 44 of cam 33, the linkage keeps locking roller 30 out of cam 29, allowing shaft 26 to rotate freely (Fig. 7, not shown)-this corresponds to movement of a sheet from pick-up to processing stations. Ramp 45 on the cam 33 then causes the roller 30 to drop into the notch in cam 29 immobilizing the shaft 26, Fig. 6; a further gentle rise in the cam from point 48 then causes link 36 to further act on rocker 31, but since this rocker is now fixed with respect to the cam 29 the entire rocker 31 and lever 40 assembly rotates slightly against action of spring 43 and causes shaft 26 fixed to lever 40 to have a correspondingly slight feed movement (Fig. 8, not shown). Rise portion 47 of cam 33 then locks the apparatus during the processing step, before the cycle recommences.

As shown a tape cartridge 12 (endless tape type) supplies tape 14 to recording station 22, developing station 24 and image transfer station 26. Image transfer is performed line by line. Copy sheet 19 which can be ordinary paper is advanced over cylinder 106 one line at a time and tape 14 is fed by drive 42 in line lengths from stack 60 to align with the paper 19. When aligned, pressure cylinder 104 performs one revolution so that flat topped cam 115 moves an advancing area of pressure through the plate 102 on to the aligned tape and paper. This causes the required image transfer, the cylinder is stopped as shown in Fig. 5 with no pressure on the paper and tape to permit them to advance.

Abstract: 938,508. Laminates. BAKELITE Ltd. July 31, 1962 [Aug. 1, 1961], No. 27838/61. Class 140. [Also in Group XXXVI] Copper faced laminates, e.g. for the manufacture of articles utilizing printed circuits, are made from Cu foil which has had its surface area increased electrolytically (see Group XXXVI) to give it improved bonding properties. A laminate may be made by moulding under heat and pressure an assembly comprising one or more layers of filler impregnated or coated with a synthetic resinous binding agent, optionally a layer of adhesive, and a layer of Cu foil. The filler may consist of paper of kraft, α-cellulose or cotton types, or of asbestos, glass or cotton fabric. The binding agent may be a thermosetting resin such as phenol-formaldehyde, melamine formaldehyde, epoxide or polyester resin or it may be a thermoplastic material such as polyethylene. The adhesive, if used, may be a synthetic rubber adhesive or a polyvinyl acetal type, preferably in admixture with phenol-formaldehyde resin. Alternatively, a laminate may be formed by moulding under heat and pressure an assembly comprising one or more sheets of thermoplastic material, e.g. polyethylene, together with one or more sheets of Cu foil. In an example, the roughened surface of a Cu foil was coated with a solution of phenol formaldehyde and polyvinyl butyral in industrial methylated spirit and xylene and the coating dried. A stack was built up from 1 sheet of the adhesive-treated Cu foil, a sheet of α-cellulose paper impregnated with melamine formaldehyde, 15 sheets of cotton based paper impregnated with cresol formaldehyde, a sheet of α-cellulose paper impregnated with melamine formaldehyde and 1 sheet of adhesive-treated Cu foil.
